The baby was found to be suffering from subdural and retinal hemorrhaging, broken bones including a broken arm and leg, compression fractures of the vertebrae and cerebral swelling, according to prosecutors.

"There was bruising under the scalp, bruising on the buttocks. Compression fractures on the vertebrae, that would be consistent with the slamming of a child," prosecutor Katherine Folger said.

The baby also showed signs of previous injuries that had started healing, prosecutors said.

The girl, who was taken to the hospital on her first birthday, was declared brain dead on Jan. 16 and taken off life support.

Defense attorney Melinda Thompson said McCarthy Brady is innocent and the injuries may have happened during family trips to Pakistan, Saudi Arabia or London while the child was not in the nanny's care. Thompson also said the baby was diagnosed as malnourished by a doctor.

"She was diagnosed by doctor as being malnourished, who suggested she not go on another trip. She went on another trip, again, without the nanny, without Ms. McCarthy, to Saudi Arabia, Pakistan," Thompson said.

McCarthy Brady, who is married without children of her own, has no criminal record and came to the United States from Ireland 13 years ago. She had worked for the family for six months.

Federal immigration officials told NewsCenter 5 that Brady was not in the country legally.
